Cylindrical Wire Electrical Discharge Truing of Metal Bond Diamond Grinding Wheels. (Under the direction of Albert Shih) The goal of this research was to use the wire Electrical Discharge Machining (EDM) to profile a metal bond diamond grinding wheel, and then study the wear and grinding performance of the EDM trued wheel.

Although centerless grinding technology has been around for 100 years since the method was patented by Heim in 1917, a great deal of effort was exerted by early research pioneers to understand its rounding mechanism, and significant papers have been published [4,5,6,7,8,9]. The theory of the rounding mechanism has been well established, the setup guidelines for achieving better roundness have been .

One research route that has been explored for about half a century is the development of additives to the grinding mill feed that substantially improve the efficiency .

Research suggests that some jointcracking sounds may be associated with the creation and/or collapse of tiny gas bubbles within the joints. Synovial joints, such as the cervical facet joints in the neck, have a joint capsule filled with synovial fluid that lubricates and protects the .

This method can dress grinding wheel inprocess, avoid microcrack that produced in traditional engineering grinding, reduce the grinding force, improve the service life of grinding wheel, advance the surface quality and machine nonconductive engineering ceramics in ultraprecision.

The removal mechanism of silicon nitride ceramic under highspeed grinding is studied in this article, and grinding parameters are optimized. The efficiency of grinding is improved. The diamond grains of grinding wheel are simplified into the truncated octahedron and cone to simulate the grinding process.

The discussion concludes that different classes of materials have distinctive material removal mechanisms in grinding and hence have their individual surface integrity characteristics. The workpiece materials to discuss include metals, ceramics, semiconductors and composites.

eruption, and by mechanical or manmade processes such as crushing, grinding, milling, drilling, demolition, shovelling, conveying, screening, bagging, and sweeping. Dust particles ... particles, diffusion becomes an effective mechanism and deposition probability is higher.

This mechanism has the disadvantage that it imposes slightly more risk on validators (although the effect should be smoothed out over time), but has the advantage that it does not require validators to be known ahead of time.

Polycrystalline diamond (PCD) grinding takes an important role in the field of tool manufacture. Regardless, there is still lack of process knowledge about the .

Mathematical Problems in Engineering is a peerreviewed, Open Access journal that publishes results of rigorous engineering research carried out using mathematical tools. Contributions containing formulations or results related to applications are also encouraged.

In addition to the Higgins Grinding Technology Center and the Grinding Technology Center at SaintGobain Research India, SaintGobain maintains a European Grinding Technology Center in Norderstedt, Germany, — also home to a BLOHM PROFIMAT MT machine — and a China Grinding Technology Center in Shanghai.
